25 Japanese Slang to Learn by 2023

Japanese slang words are often made by a combination of Japanese and English. Knowing the slang of a particular country can make conversations feel more friendly and informal. In Japan, slang should only be said to close friends and relatives as they can be considered rude if you say it to someone in a higher position than you.

New abbreviations and phrases are constantly being coined and created every day and as the New Year is approaching, here are some of the must-know Japanese slang to get you one step closer to sounding — and feeling — like a native.

1. 若者言葉 (Wakamono Kotoba) – Used by Young People

若者言葉 (Wakamono Kotoba) is a Japanese slang that is mainly said by — you guessed it — young people. The literal translation? Words of the young people. Here are the more common wakamono kotoba that are short forms of Japanese words and phrases.


っす(ssu) is the short form of the copula”です” in oral Japanese and is usually used by young men. “っす” is not considered as a form of polite speech hence it can sound rude to certain people.

Some examples of how to use “っす”
